The SE 06 together with the SE 05, and SE 07 dining chairs and the TE 06 dining table were designed by Martin Visser for Spectrum in the 1950s and 60s as well as the fauteuils SZ 01 and SZ 02. The furniture is named after a simple system where the first letter ( in Dutch) indicates the type of furniture; b (bed)=sofa, s (stoel)=chair, and t (tafel)=table. SE is a chair for the dining room and SZ a chair for the living room. The two digits indicate the model.
